327 block numbers

[KTM]

There is 327 block # 3782870 witch might be very nice for my ´65. Date is A135, so it is made January 13th 1965, but front rh-side VIN Code/suffix area is very interesting. Usually there is A1234BC style code, but here is 855655249. Is this some Canadian system or what?

This block was used on 62 through 65 Corvettes but the stamping pad makes no sense. I have never seen anything like those numbers.

stamp pad number is probably some rebuilders internal tracking number.
